6-Substituted 10β-alkynylestrene derivatives of fiormule (I):
wherein
X is hydrogen, C1-C4 alkyl or halogen;
n is zero, 1 or 2;
Y is an oxo group or a methylene group;
the symbol indicates a single bond or a double bond;
R, is halogen, azido or a group
wherein each of R3 and R4 is, independently, hydrogen or C1-C4 alkyl, or R, may be divalent and is a C1-C6 alkylidene group; and R2 is hydrogen or, when R, is halogen, R2 may also be the same halogen as R,,
and the pharmaceutically acceptable salts thereof; are aromatase inhibitors and can be used, e.g., in the treatment of hormone-dependent tumors and prostatic hyperplasia.
